Trouble with regular expressions

Hi, I'm quite new to regular expressions, and I wonder if anyone here could help me out. I'm looking to split strings that ideally look like this: "Update: New item (Household)" into a group. This expression works ok: '^(Update:)?(.*)(\(.*\))$' - it returns ("Update", "New item", "(Household)")

Re: Calculate sha1 hash of a binary file

I did some testing, and calculating the hash value of a 1Gb file does take some time using this method. Would it be wise to calculate the hash value based on say for instance the first Mb? Is there a much larger chance of collusion this way (I suppose not). If it's helpful, the files would primaril

Calculate sha1 hash of a binary file

Hi - I'm trying to calculate unique hash values for binary files, independent of their location and filename, and I was wondering whether I'm going in the right direction. Basically, the hash values are calculated thusly: f = open('binaryfile.bin') import hashlib h = hashlib.sha1() h.update(f.re

Reproducing a web page and add own content to it.

Hi - I'm working on a Django powered site where one of the required functionalities is the possibility of displaying the content of external pages, with an extra banner at the top where specific information is displayed. In other words, I'm looking for a way to reproduce an existing web page and a

Heh, a description of the error would be nice indeed. Just a preliminary warning: with this code you will also be parsing directories. id3reader can't handle those ofcourse. Better add a check such as eg: if os.path.isfile(os.path.join(directory, file)): # do your thing laundro -- http

VLC-python bindings

Hi, Has anyone succeeded in compiling the vlc-python bindings on Windows? (as discussed in the vlc development wiki). I have found several compiled bindings, but none were updated for Python 2.4 (or 2.5 for that matter). As I am a complete layman for everything that is C compilation on any platfo

Re: Help me understand this iterator

Thanks all, those were some great explanations. It seems I have still still a long way for me to go before I grasp the intricacies of this language. That 'magic index' variable bugs me a little however. It gives me the same feeling as when I see hard-coded variables. I suppose the generator class

Re: Help me understand this iterator

Ack, I get it now. It's not the variable's name ("index") that is hard-coded, it's just that the for...in... loop sends an argument by default. That's a lot more comforting. -- http://mail.python.org/mailman/listinfo/python-list

Help me understand this iterator

Hi, I've found this script over at effbot (http://effbot.org/librarybook/os-path.htm), and I can't get my head around its inner workings. Here's the script: import os class DirectoryWalker: # a forward iterator that traverses a directory tree def __init__(self, directory): self.

What value should be passed to make a function use the default argument value?

Suppose I have this function: def f(var=1): return var*2 What value do I have to pass to f() if I want it to evaluate var to 1? I know that f() will return 2, but what if I absolutely want to pass a value to f()? "None" doesn't seem to work.. Thanks in advance. -- http://mail.python.org/mailma
